Conan: Live in the Maori Detective Agency at the beginning

"That's what I mean." said the woman in the yellow sweatshirt.

"But, Miss Mai, why were you the only one who went to buy drinks for four people? It must be too hard for you to get four drinks by yourself." Kogoro Mouri noticed the blind spot and asked.

Hong Shangwuyi, the woman in the yellow sweater, said, "Because there were so many people, I asked everyone to go to their seats first."

"Later, Urata came to see me..." Mai Hongjo roughly recalled the situation at that time. Mr. Urata originally came to help get drinks, but when he saw certain people, he walked away with a grim face.

"Bluish face?" Inspector Megure was surprised to hear this description.

"Has something happened?" asked Kogoro Mori.

"I think he must have seen that I was also selling drinks at the counter at that time." A short-haired female high school student wearing round-frame glasses and school uniform suddenly said.

Everyone heard the voice and turned to see her standing in front of them.

Noda Romi also recognized her and said in surprise: "Oh, it's Ayako. I didn't expect you were also a student of this school."

"No wonder, I thought I'd seen you somewhere." Hong Shang Mai walked up and said.

"Huh?" Xingchen blinked and thought, it's the big sister who sold them drinks.

"How many of you know each other?" asked Officer Megure.

"Yes, this lady is the only daughter of our hospital director." Noda Luomei responded.

"So the person who added drinks for the four of them just now was..." Kogoro Mori looked at Ayako Ninagawa and asked.

"It's indeed me." Ninagawa Ayako put her hands in front of her and nodded in response.

"I see. Now all the suspects are here." Hattori Heiji said, looking at the four people.

"What are you talking about? Mr. Urata and I both ordered iced coffee." Hong Shang Mai patted her chest and said, "If I poisoned his coffee, I could have just given it to him so that he wouldn't accidentally drink the poisoned drink."

"But you could also poison both cups and just not drink yours," Inspector Megure made a guess.

"But I drank it all." said Hong Shang Mai.

"You didn't pour your cup into the bathroom," asked Kogoro Mouri.

"I told you, I went to the restroom after I handed everyone's drinks to Mitani." Hong Shang Mai emphasized again: "After I came back, the show started, and I never left since then."

"I was just distributing the drinks she gave me to everyone, so there was no time to poison them." Mitani Yota explained quickly.

"I don't have that opportunity either." Noda Romi also said quickly.

They were all afraid that they would be mistaken for the murderer and explained quickly.

"But at least you opened the lid of the cup to make sure what kind of drink was inside." Officer Megure asked Mitani Yota.

When Mitani Yota was about to answer.

"No, Officer Megure. Look, this is the drink that Sister Kazuha and I bought. Look, the name of the drink is written on the bottle cap." Xingchen held up her oolong tea and handed it to Officer Megure.

"Besides, there's creamer or syrup on the coffee." Conan said lightly.

"I see." Inspector Megure took the bottle and looked at the words on the bottle cap and replied.

"You may have prepared creamer and syrup mixed with poison in advance." Maori Kogoro guessed, "Just switch them before giving them to him."

"Shouldn't he have died immediately after drinking it?" Noda Luomei retorted, "Isn't potassium cyanide a fast-acting drug? But Dr. Urata drank almost all of the drink."

"Ah..." Kogoro Mori couldn't think of any other possibilities.

"I'm not sure what method the murderer used to make Dr. Urata take the poison, but I can be sure that the murderer is among you four." Hattori Heiji said nonsense.

Xingchen touched his chin. He thought of several methods. The first one was to use capsules and mix them into the medicine the doctor took.

But this doctor probably hasn't taken any medication or anything like that, so this can't be true.

The second method is to inject the drug into a hollow ice cube. When the ice cube melts, the poison will be integrated into the drink and become indistinguishable from the other.

But this is how the murderer distinguished the poisoned ice cubes in the cup of ice coffee, which made Xingchen confused. Wasn't the murderer afraid of killing the wrong person, or even killing himself?

There are two people who have the opportunity to put poisoned ice cubes into the drinks now. The first one is Miss Hong Shang Mai who bought the drinks.

The other is Ms. Ayako Ninagawa who sells drinks. These two are the most suspicious persons.

It is quite difficult for others to put in the poisonous ice cubes.

"Inspector, we found some unused creamer and syrup in Mr. Urata's pocket." Takagi Wataru half-squatted on the ground, holding the creamer and syrup in his hand and said.

"It hasn't worked yet. What's going on?" Inspector Megure was confused. How could an ordinary person drink iced coffee without creamer or syrup?

"Then let me ask, Mr. Urata, do you usually drink black coffee?" Hattori Heiji looked at the four people and asked.

"No, I remember he usually adds creamer and syrup to his coffee." Noda Luomei confirmed with the others: "Right."

"Yes, he does add both." Mitani Yota also agreed.

"Then...how come he had both left?" Kogoro Mouri said in confusion.

"That's because... because there's not iced coffee in the cup, but cola." Ninagawa Ayako suddenly said.

Xingchen was speechless and asked, "Girl, why didn't you say it earlier?"

Everyone was also surprised and expressed doubts.

She went on to explain: "I thought that he would come to me to exchange a cup of coffee."

"Maybe he will come and ask me why I broke off my engagement with him." Ninagawa Ayako said with a somewhat melancholy look on her face.

"You mean an engagement!" Inspector Megure said with some surprise, because the age difference between the two is almost ten years, and this kind of engagement is rare.

As we all know, 22 years ago, Japanese women could get married at the age of 16 and men at the age of 18.

But generally they are well matched in terms of family background or age difference.

Although 22 years later both men and women can get married at the age of 18.

"That's right." Ninagawa Ayako nodded and continued, "I originally planned to marry him right after graduation."

"But I suddenly feel uneasy," Ninagawa Ayako looked at the ground, as if she didn't want to face the matter directly, and said, "Last week, I called to reject the marriage proposal. Since then, every time I went to the hospital, he avoided me."

"No wonder, my cup also contained Coke." Hong Shang Mai took out creamer and syrup from her pocket and said, "Just now, I almost put creamer and syrup in it."
